Patented Apr. 25, 1933 warn-:1) STATES PATENT OFFICE] FRANK O NEILL, 0F TOLEDO, OHIO GLASS BLANK TRANSFER ori inal application and August 19,

.; This invention relates to the control'in' determined sequence of various devices in series provldmg an automatic complete apparatus, as for performing successlvely opg thrown closed blow mold of Fig. 1; and

Fig. 3 is a fragmentary detail of the slide mounting of the radially movable blow mold of Fig. 1. The feature of transfer herein disclosed may be brought about by an actual movement of the blow mold over to receive the suspended blank at the region of proximity between the tables. In such embodiment there is provided below the table an inclined cylinder 270 to which line 156 extends for a timely supply of power air. This power air causes piston rod 271 to be drawn into the cylinder 270, thereby rocking the angle lever 272 engaging between the pair of 30 prongs 273 of a downwardly proecting fork upon aslide 274 reciprocable ra ially of the column 36 in This slide 274 carries. a base 276 upon which is mounted below mold sections 197 and the control mechanism therefor. In the guides 275 carried by the table use of the term blow mold sections such is herein used'to mean. a succeeding, 'a finish forming or an additional operation after the 40 blank forming. The cylinder 270 and the v a toothed portion 279 lever 272 are carried by ab'racket 277 mount- 7 ed on the column 36 below the table 35. In order that there may be clearance for this inder 270, the table-35 carries a downwardly extending flange or skirt 278 terminating in in mesh with intermediate driving gear 32. I

1918, Serial No. 250,488. Divided and this application filed Sep'uhnber 7, 1929. Serial No. 390,956. r

the region of cam portion 236 to the transfer for receiving a blank from the table having the gear 17, are partially closed by the cam portion 261, while after being closed about the blank at the transfer station, in

. then riding therefrom about the cam 235, a

spring262 about the rod 234 yieldably maintains this closed relation. The partial closing of the blow mold sections 197 by riding on the cam 261, leaves a minimum of opening for supplying the blank thereinto, while the remaining short travel distance for complet lng theclosing may occur rapidly without seriously hammering the sections against each other, for the movement is so slight.

Inthis outward thrust, the blow mold sections 197 are open sufiiciently wide to embrace the suspended'blank held by the neck mold sections 117, 118.

" In sequence thereafter power air from line 166 enters the outer end of horizontal cylin-- der 280 carried by'a bracket 281 for extending radially away from the column 36. This power air causes piston rod 282 to travelinto the cylinder 280, rocking lever 283 fulcrumed in the bracket 281, so that the'lower end of the lever 283 engages behind or on the inner side of the roller 232 as carried out on the I base 276. This roller 232 moves outward with the slide 233 on which the rolleris mounted. Spring 262 is about the rod 234 which rod extends freely through the crosshead 194. The spring 262 thus actsyield- .ingly to thrust the crosshead 194'outwardly.

The crosshead 194 acting through the .ad-

justable links 195 yieldably closes the blow.

niold sections 197 about the blank. I

Simultaneous with the embracing of the blank in the blank mold sections as sustained by the neck mold sections 117 118, or properly timed therewith, occurs the downward travel of plunger 176 from the cylinder 174 'as effected by line 199 from a port medially of the length of the cylinder 280 extending to the cylinder 174. This travel of the. plungor 176 opens the neck mold sections 117,118, thus. releasing the blank into the blow mold sections 197 as closed thereabout.

Line 249 from the distributing valve (see 39 in United States Patent 1,602,906, October 12, 1926), in this instance leads to the after end of the cylinder 270, eflecting an outward throw of the piston rod 271 and a rocking of the lever 272 fulcrumed in the bracket 277 for drawing the closed blow mold sections 197 with the blank therein back into position upon the table 35. Simultaneously air is supplied to the inner end of the cylinder 280 by branch line 284 from the duct 249, thus getting the lever 283 out of the way of the roller 232 and resetting this final blow mold closing device for the next operation.

As the next gather of molten glass is charged into blank mold sections 95, 96, and there occurs the! next 60 Travel step of the table 35, the forks 273 ride clear of opening 287 to embrace upstanding flange 288 mounted against rotation on the column 36 below the table 35. The base 276 is accordingly positively held against radial travel.

The vertical adjustment of the second table 35, with its gear-34 as readily permitted by the long teeth of the intermediate gear 32, in the taking care of different lengths of ware, is readily accomplished by the insertion or removal of washers below the bearing on the column 36 sustaining the table 35. There is interconnection for common simultaneous travel of the tables.
